“…4d), which proves that abiotic N 2 O was solely produced by NH 2 OH. These results correspond well with data from Bremner et al (1980). They reported that, independently from the presence of NO À 2 , NH 2 OH was rapidly converted to N 2 O (most of it within the first hours after NH 2 OH application) when applied to a sterilized soil.…”

“…While in experiment I, N 2 O release was only related to added 15 NO À 3 , in Experiment IV the N 2 O release revealed a clear incorporation of an unlabeled N source (i.e., NH 2 OH). It was already reported by others (Bremner et al, 1980;Nelson, 1982;Bremner, 1997) that NH 2 OH can be rapidly converted to N 2 O due to an abiotic redox reaction with oxidized metal species (e.g., Mn). A similar abiotic N 2 O formation was found in Experiments III (only 15 NH 2 OH; autoclaved) and V ( 15 NO À 3 + NH 2 OH; autoclaved).…”

“…As already shown by others (Lees, 1952;Verstraete and Alexander, 1972), NH 2 OH is an essential intermediate during the nitrification process. In addition, it has also been proven to be directly involved in soil N 2 O production via nitrification (Khalil et al, 2004) as well as via abiotic NH 2 OH decomposition (Bremner et al, 1980;Nelson, 1982).…”

A few studies have shown that amine compounds (e.g., hydroxylamine) can be co-metabolically introduced into the reaction pathway of denitrification. During this microbial process, the N atom of the amine species is bound to a N atom of nitrite. In case of hydroxylamine, this concomitant reaction ultimately results in the formation of hybrid N 2 O. Due to its co-metabolic character the process has been termed co-denitrification. Hybrid N 2 O production during co-denitrification has been proven to occur in prokaryotic (e.g., Pseudomonas sp.) as well as eukaryotic (e.g., Fusarium sp.) species. Many of them are already well-known as common denitrifiers. However, until now no clear evidence has been provided to show that N 2 O production by co-denitrification really takes place in a soil. In the present study, a formation of hybrid N 2 O was revealed by an adapted 15 N-tracer model, when both hydroxylamine and 15 N-nitrate were applied (mol ratio 10:1) to an anaerobically incubated soil suspension from a Haplic Chernozem. The presence of hybrid N 2 O was also indicated by a novel characteristic factor (R binom ) developed for a hybrid-N-N-gas detection. By contrast, no hybrid N 2 O was found when either an autoclaved soil suspension, only nitrate or only hydroxylamine was used. Thus, it appears that hybrid-N 2 O formation occurred due to co-denitrification of hydroxylamine. Hence, this is the first study which demonstrates hybrid-N 2 O production by co-denitrification beyond a microbial species level. The 15 Ntracer model revealed that under the given experimental conditions N 2 O production by co-denitrification prevailed against N 2 O from denitrification and abiotic hydroxylamine decomposition. In addition, a formation of hybrid N 2 was also calculated by the model. However, the experimental results lead to the conclusion that it was most likely caused by a reduction of hybrid N 2 O due to conventional denitrification.

“…The mechanism of N 2 O production from nitrification has not been systematically determined (Khalil et al 2004;Shaw et al 2006). The oxidative decomposition of hydroxylamine (Bremner et al 1980;Hooper and Terry 1979) and nitrifier denitrification (Poth and Focht 1985;Zhu et al 2013a) (i.e. denitrification by ammonia oxidising bacteria, as proposed by Baggs (2011)) have been implicated, with a key role for nitrite suggested (Mørkved et al 2007).…”

The roles of abiotic factors such as metal ion species, including iron III and manganese II, in the oxidation of hydroxylamine (Hooper and Terry 1979;Bremner et al 1980;Zhu et al 2013b;Heil et al 2015), chemical or thermal decomposition of hydroxylamine, and processes such as nitrifier denitrification under conditions of oxygen stress have not been widely acknowledged or included in models. Consequently, most models adopt a grey-box approach to predicting N 2 O from nitrification, allocating a set proportion of nitrified N to N 2 O emission (P n in Fig.…”

Abstract. Laboratory incubations were performed to estimate nitrification rates and the associated nitrous oxide (N 2 O) emissions under aerobic conditions on a range of soils from National Agricultural Nitrous Oxide Research Program field sites. Significant site-to-site variability in nitrification rates and associated N 2 O emissions was observed under standardised conditions, indicating the need for site-specific model parameterisation. Generally, nitrification rates and N 2 O emissions increased with higher water content, ammonium concentration and temperature, although there were exceptions. It is recommended that site-specific model parameterisation be informed by such data. Importantly, the ratio of N 2 O emitted to net nitrified N under aerobic conditions was small (<0.2% for the majority of measurements) but did vary from 0.03% to 1%. Some models now include variation in the proportion of nitrified N emitted as N 2 O as a function of water content; however, strong support for this was not found across all of our experiments, and the results demonstrate a potential role of pH and ammonium availability. Further research into fluctuating oxygen availability and the coupling of biotic and abiotic processes will be required to progress the process understanding of N 2 O emissions from nitrification.

Soilborne pests are a major obstacle that must be overcome for the production of horticultural crops. Methyl bromide (MBr) was an effective preplanting soil broad‐spectrum biocide, but its use has been banned due to its role in depleting the ozone layer. As a result, sustainable alternative methods for controlling soilborne pathogens and pests are needed. Nitrous oxide (N2O) emissions are of concern in crop production due to the role of N2O as a greenhouse gas. Agricultural lands are known sources for emission of N2O into the atmosphere. Emissions are related to many environmental factors as well as fertilization and fumigation practices. This study evaluated the influence of different alternatives to MBr on N2O emissions throughout a tomato production season in two locations representative of southern and northern Florida. We evaluated eight soil management practices, including (a) untreated controls; (b) chemical soil fumigation; (c) anaerobic soil disinfestation using molasses (M) + composted poultry litter and (d and e) M + composted yard waste (CYW, at two rates); (f) Soil Symphony Amendment (SSA), a commercially available mix of microbes and nutrients; (g) CYW alone; and (h) CYW + SSA. Nitrous oxide emissions were measured throughout the cropping season. Emissions were highest on the day of planting (Day 21), ranging from 213 to 1,878 μg m–2 h–1, likely due to the release of N2O that had accumulated under the totally impermeable film when it was punctured for planting. However, statistical significance varied between sites. Estimated cumulative emissions of N2O throughout the production season ranged from 1.3 to 4.8 kg N2O–N ha–1.
